正确的写法，汗，居然这么简单！ package oddEven; import java.util.Scanner; import java.util.Random; public class oEven { public static void main(String[] args) { try { Random ran = new Random(); Scanner scan = new Scanner(System.in); System.out.println("请出拳：1剪刀，2石头，3布");//这里加一句 while (scan.hasNext()) {//终于明白hasnext（）的意思了。原来是这样的，需要输入，谢谢。 int person = scan.nextInt(); System.out.println("人：" + person); int computer = ran.nextInt(2) + 1; System.out.println("电脑:" + computer); if (person == computer) { System.out.println("你出的" + getName(person) + ";电脑出的：" + getName(computer) + "。你两弟兄打成平局"); } if (person == 1 && computer == 3) { System.out.println("你出的" + getName(person) + ";电脑出的：" + getName(computer) + "。你赢了，该你笑！"); } if (person == 3 && computer == 1) { System.out.println("你出的" + getName(person) + ";电脑出的：" + getName(computer) + "。你输了，该你在宝马里面哭！"); } if (person == 2 && computer == 3) { System.out.println("你出的" + getName(person) + ";电脑出的：" + getName(computer) + "。你输了，该你在宝马里面哭！"); } if (person == 3 && computer == 2) { System.out.println("你出的" + getName(person) + ";电脑出的：" + getName(computer) + "。你赢了，该你笑！"); } if ((person == 1 && computer == 2) || (person == 2 && computer == 1)) { System.out.println("你出的" + getName(person) + ";电脑出的：" + getName(computer) + "。尼玛，你两弟兄真是极品，不带这样玩的！"); } System.out.println("请出拳：1剪刀，2石头，3布");//执行了后再次输入这句话就可以连续起来了。 } scan.close(); } catch (Exception e) { e.printStackTrace(); } } public static String getName(int number) { String name = ""; switch (number) { case 1: name = "剪刀"; break; case 2: name = "石头"; break; case 3: name = "布"; break; default: break; } return name;/* 哪有问题 不要进调试模式 像这样 右键 run as javaapplication */ } }
